I have 2 Goodyear Wrangler HP 255-55-19 tyres. One has been my 'new' spare and has literally been used for a week or so and has 10mm of tread. The other has at least 5mm remaining. They have NO damage whatsoever, all tread is even and they have never been repaired. Advertised price is for the 10mm tyre or 35 quid for the 5mm tyre. I'll do a deal for the pair. These are 130 pounds each new. Bargain!
